Question

1. A ____ current means that more _____ flows per second.

2. A student connects up an ammeter in a circuit with a lamp and a cell. The reading is 0.5 A. She moves the ammeter to the other side of the lamp.

a. What will the ammeter read now?
b. Explain your answer.

Answer 1

1. An electrical current means that more electrons flows per second.

2. a. 0.5 A

b. Because current always stays the same in series

circuits.

Answer 2

1.

A stronger current means that more charge flows per second.

2.

a. The ammeter will read the same, 0.5 A.

b. The ammeter measures the flow of electric charge in a circuit, which is called the current. The amount of current in a circuit depends on the properties of the components in the circuit, not the position of the ammeter. Therefore, moving the ammeter to the other side of the lamp will not change the current flowing through the circuit, and the reading will remain the same.
